Notes:
Structure investigation results for MASHS powder Fe40Al/Al2O3 are presented. Thepowder structure formation proceeds via two stages. On the first step (mechanical activation)aluminothermal reaction takes plays in the system Fe+Al+Fe2O3, leading to formation ofnanocomposite precursor Fe-Al-Al2O3. On the second step (SHS), iron and aluminum reacts,forming intermetallic FeAl. As-synthesized composite powder completely inherits the precursorstructural morphology in spite of the phase transformations taking place during the productionprocess. Such a production route provides the formation of intergrowth nanocomposite materialstructure with improved interfacial strength
